qRegisterMetaType- reference as argument in connect throwing run time error

Then you should probably not have used a local variable definition.

@prasad_N:
Or at least written it as a commented-out line, with an explanation that "obj" is a class member variable. How are we to understand that when you write it as you did, you weren't posting your actual code? A lot of the discussion here was based on your incorrect posting, and it could have been avoided if you had posted the actual code in the first place.

C++ programmers can also use pointers and can use references for the special case where the alias can be initialized with the address of the object, e.g. passing a reference to a constructor, storing it in a reference member.

And this has the added benefit over storing a pointer member variable in that you are absolutely assured that the member variable is a valid reference to an object instance, whereas anything can be assigned to a pointer member, including nothing.

There was a mistake & people are over emphasizing on that rather than a actual question, Anyhow I will take care from next time while posting.

It depends on your requirements.
If you want the slot to execute in the context of the emitter thread, use a direct connection.
If you want to use the signal/slot bridge as a mean to conveniently copy data between threads, use a queued connection.

None of them are not my requirements. As per my requirement & Replay's from you guys I think there is no solution for this at least for now (passing reference across threads if it it is queued connection).

Yes, the only reference that can be stored is a pointer.

Cheers.
